The Emax F4 Magnum Mini is a solid stack of FC, ESC and video transmitter in one, especially suitable for 3-4" copters, cinewhoops and 5" ultralights. The basis is a FC with an F4 processor and a reliable MPU6000 gyro. The board has an OSD, 2 LEDs and a powerful 5V 3A BEC. The biggest advantage of this stack are the ESC. They use BlHeli_32 firmware, also support 6S and can handle a load of up to 35A. Two capacitors then take care of filtering the input voltage. The stack also includes a video transmitter with a u.FL connector and a power of 25/200mW. The video transmitter supports Smart Audio protocol settings.
